miren BLOOMFIELD H. HOWARD, OF W Application filed December res FEEDER FOR Be it known that we, BLooMFinLD H.

HOWARD and ERNEST J. TURNER, citizens of the United States,V resi lVashington, District ding, respectively, at of Columbia, and

Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and usefn Feeders for Ingot Mol l Improvements in ds7 of which the following is a. specification.

Our invention relates to improvements in feeders for ingot molds.

The object of our vide a feeder for ingot molds adapted invention is to prorest upon the upper endof thev mold, and having a portion extending into the bore Another object of ou the mold whereby piping is and segregation is reduced to a prevented minimum. is to prowliich the r invention upper end is provided with a thickened `portion to of refractory material the upper end of the and at the same time supporting the feeder the mold.

provide for a sufficient amount to retain the heat at mold and the ingot, providing means foi in the upper end of A further object of our invention is to provide a feeder of this character adapted to tightly fit on the upper end of the mold, the bores ofY which vary slightly, and

adapted to have a hold the feeder on th A still further to provide a simple7 feeder having certain wedging action to tightly e mold.

object of our invention is cheap and effective details of structure and combination of parts hereinafter more fully set forth.

In the accompanying drawings:

Figure 6 is a bottom plan view of a circular feeder showing the same principle as that shown. in Figures 4 and 5.

Referring now to the drawings, l represents the mold and 2 the feeder, which as shown is of a tubular form having the thin portion 3 extending into the bore of the mold, and a thickened portion l at its upper end. rFhis thickened portion provides a large amount of refractory material to retain the heatl at the upper end of the mold to prevent piping and segregation iii the iiigot, and also serve as means for supporting the feeder on the upper end of the mold. The lower face of the enlarged portion l has two faces 5 and 6 which terminate at the outer periphery of the thin or neck portion 3 of the feeder. By this structui'e it will be seen that there is a wedging action between the upper end of the mold and the face 6 of the enlarged portion fl. If the mold was of a diameter to engage the face 5 of the thickened portion 4 there would also be a wedging action to canse the feeder to center itself in the mold and be held against lateral movement.

In the modification shown in Figure 3, the same principle is employed, except that the feeder is made ina circular forni and in foiir sections 7,8, 9 and l0, the thickened portion having two surfaces the same as that shown in F ignres l and 2 and like reference numerals indicate like parts. In the modification shown in Figure et. the cylindrical body portion 3 is provided with the thickened upper end 4, the. lower face of which is provided with three faces l1, l2, and 13 whereby the feeder is tightly held in the bore of the mold regardless of the diameter of the horn, of the mold.

In the modification shown in Figure 6, we have shown a circular sectional feeder made in four sections 14, l5, 16 and 1T, and each section having' the thickened portion l the saine as that shown in the other figures, having its lower end provided with three surfaces the same as shown in Figures l and 5.

Having thus fully described our invention what we claim is l. A feeder for ingot molds comprising a tubular body portion having a thickened uppfr end, the lower face of said thickened portion having a series of plane surfaces. V2. A feeder for ingot molds comprising a tubular body portion having a thickened portion, the lower surface of which is con= nected with the tubular portion by a series of plane faces. Y

3. A feeder for ingot molds comprising a tubular body portion having a thickened portion, the lower face of the thickened portion having a plurality of surfaces extending from the outer face of the thickened portion to the outer face of the thinner portion.

4. A feeder for ingot molds comprising a tubular body portion made of several sections, and having enlarged portions, the

lower faces of the enlarged portions having a series of plane surfaces.

5. A feeder for ingot molds comprising a tubular body portion formed of a series of` sections having enlarged upper portions, and having their lower faces provided with a series of plane surfaces.- l

6. A feeder for ingot molds comprising a tubular body portion made of refractory material, a relatively thick upper portion, a relatively tliinlcwer portion, these two portions connected by al series of plane surfaces.

In testimony whereof we affix our signatures. BLOOMFIELD H. HOWARD. ERNEST J. TURNER.
